Question

How many students text during class? A student created an anonymous survey asking students whether or not they text in class. Of the 50 students who responded, 64% said they text in class.
Is this a categorical or quantitative variable?



How many students responded yes? How many said no?






Calculate the margin of error.






What does the margin of error mean in the context of this problem?.





How can you decrease the margin of error?





Calculate the 95% confidence interval for students who said YES they text in class?




Write the 95% confidence statement for the problem above.

Answer 1

Answer:

1 quantitative

2 32 responded yes, 18 responded no

3 margin error 32%{n}

4 error of students on their phone / not

5 18/-/50

6 16%

7 2%

Step-by-step explanation:

a 95% confidence interval with a 4 percent margin of error means that your statistic will be within 4 percentage points of the real population value 95% of the time.

The margin of error tells you the range of values above and below a confidence interval.
